[Csnd] Basic MIDI controller issue

The Csound Mailinglist
1

Hi all,

I am not able to get MIDI controllers to work. I’m on Win11 and I have three devices connected (a keyboard and two controllers). All three are working properly according to MIDI-OX. Both controllers are configured with a knob set to use CC 11, verified in MIDI-OX.

Here’s a simple test program based on examples in the manual. When I run it, the instrument runs when I press a key, and I’m getting note and velocity data. But kamp never changes. What am I missing? Result it the same whether or not I explicitly set -+rtmidi. See console output below the code.

-d -m7 -odac1 -+rtmidi=portmidi -Ma ; -d -m7 -odac1 -Ma sr=48000 ksmps=1 nchnls=2 0dbfs=1

instr 1
imax = 1
imin = 0
ictlno = 11

; ipch pchmidi
icps cpsmidi
ivel veloc
prints(“icps=%f ivel=%f\n”, icps, ivel)

kamp midic7 ictlno, imin, imax
; ktrig changed2 kamp
; printks(“ktrig=%f kamp=%f\n”, 1, ktrig, kamp)
printk2 kamp

asig oscili kamp, icps, 1
outs asig, asig
endin

Hi Dave,
to me works well, of course I must held the note. Normally I use ctrl7, in order to control better the Midi channel.
greetings

Thanks, Giovanni. I have tried ctrl7 with the same result.

I added a call to midin to see what the raw MIDI input looks like. Very interesting – I am getting data from the controllers, but the status byte is always 0 rather than 176 (B0 control change). This explains why I’m not getting the CC changes, but it raises the question – why is Csound getting status=0 for all these messages? In MIDI-OX, I can see status byte B0 whenever I move a controller.

Did you try selecting a single device at a time?
Maybe -Ma is the problem.

What version is this?

Aha, that is the issue, thanks Victor. This is with Csound 6. Although this is a workaround, it’s not a good solution because my keyboard has no knobs/sliders. My LaunchControl has both buttons and knobs, and I was able to use it, but I want the features of my K-Board – buttons are not as good as a real keyboard.

It would be nice if one could select multiple specific devices, e.g. “–midi-device=3,4” but that would be a feature request.

Should I enter a ticket for the -Ma issue?

7

Probably a good idea.

The odd thing is that it affects control change but not note on/off. The portmidi module code does make any distinction between the two.

I just tested it on the Mac with two separate devices and -Ma and I can’t reproduce the problem. I can receive channel messages alright.

10

Well, it may only be on Windows. I’ll try to test it tomorrow on a Raspberry Pi, which is the only *ix system I have currently.

11

OK, I have narrowed it down to the keyboard I was using, a McMillen K-Board. If I switch to a Korg nanoKey2, then I am able to use both the keyboard and an additional controller. So it’s something about this keyboard, which I hope I can fix through configuration.

12

Interesting, but midi-ox does not have a problem with it, so?

Prof. Victor Lazzarini
Maynooth University

13

Right, so it is apparently a problem with the keyboard itself.

14

In other words, not a Csound issue per se.

15

It doesn’t make sense to me yet, but the problem doesn’t recur with the McMillen QuNexus or the nanoKey.

16

Just a gut feeling: maybe an issue with "running status" omitting resending the status byte if command and midi channel are identical to the previous one? Some devices do use running status, others don't...

Best, Jana
